P0052 Volvo Code - HO2S Heater Control Circuit High Bank 2 Sensor 1
Quick Answer
Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. Common causes include Heated Oxygen Sensor (H2OS) Bank 2 Sensor 1 harness is open shorted to ground, Heated Oxygen Sensor (H2OS) Bank 2 Sensor 1 circuit poor electrical connection, Faulty Heated Oxygen Sensor (H2OS) Bank 2 Sensor 1. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0052 Volvo Description
In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.
The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.
What are the Possible Causes of the DTC P0052 Volvo?
- Heated Oxygen Sensor (H2OS) Bank 2 Sensor 1 harness is open shorted to ground
